Diving the Great Barrier Reef with Cairns Dive Centre, Cairns, Queensland, Australia. Published 26/12/2012 at 1000 × 750 in Cairns, diving the Great Barrier Reef and Hippie Camper time! The next day we did a shallower dive and so could take our underwater camera down with us. It’s always little eerie looking up at the bottom of a boat.
